We've been covering changes to Legendary items in Patch 7.2 since the early builds of the patch. Over time, we learned a lot of interesting changes, including, but not limited to functionality, bad luck protection, Legendary targeting and crafted Legendary items.

This is a summary of all changes so far.

Bad Luck Protection

Will no longer be class-based, but spec-based

The system evaluates how many Legendary items you acquired per spec

If you have, let's say, 2 Legendary items for Enhancement and 0 for Restoration, the game will handle bad luck as if you didn't have any Legendary items yet when you switch to Restoration.

On the other hand, if you have a shared Legendary item (beneficial to several specs) and one for Enhancement, the game will handle it as though you had 1 when you switch to Restoration.

Crafted Legendary Items

Introduced to keep Professions relevant

Based on the latest Q/A, they should be solid "mid choices" (they're not supposed to be best Legendaries you can get)

Let's look at Vigilance Perch. It increases your movement speed and at 5 stacks when out of combat, you turn into a spirit owl for one minute. When the effect ends, you take fall damage.

Legendary Items Targeting

Slot targeting is now available via Relinquished items that cost 5,000 Nethershards each. The items can be purchased from Thaumaturge Vashreen. You get Nethershards by participating in various 7.2 content such as demon assaults, scenarios, Legionfall world quests and by killing mobs/rare elites on the Broken Shore. Relinquished items may contain a Legendary item.

New affix: Each time Arcane Missiles hits an enemy, the damage of your next Mark of Aluneth is increased by 1.0%. This effect stacks.

Shard of the Exodar- Your Time Warp does not cause Temporal Displacement on yourself and is not will be applied to yourself at 25 sec duration when you are affected by Temporal Displacement or similar effects on yourself.

Monk

Drinking Horn Cover - The duration of SerenitySerenity is extended by 0.4 0.3 sec every time you cast a Chi spender.
